The invention relates to a mixing device, and more particularly to mixing device for carburetors.

Object:

Among the principal objects the invention has in view are: to provide means for more effectively and more quickly vaporizing the fuel mixture passing into an internal combustion engine; to take fulladvantage of the heat present in the intake manifold; to force the fuel into direct contact with the walls of the intake manifold; to augment the breaking influence exertedupon thefuel by a mechanical device with a cross-current of incoming air; to provide a device which is readily attached, which has no movingparts,

which is permanent and which requires no alteration in the construction in the manifold or carburetor; to secure simplicity of construction and operation;land to obtain other advantages and results as may be brought out in the following description.

In the drawing: l Figure 1: is a sectional view of a portion of a carburetor and intake manifold of an in-' illustrated in said drawing, the reference numeral 10 indicates a substantially flat body portion having very much the shape of a gasket, such as would be includedbetween the flange 11 of an intake manifold 12 for an r internal combustion engine and a similar flange 13 on a carburetor of which a portion 14 is shown in the drawing. The said body portion in use is included flatwise between the said flanges with a gasket 15 below the said body portion butpreferably with no gasket above the bodyportion. The flanges, gasket and body portion are then secured fiatwise togetherby the usual bolts 16.

The said body portion 10 aside from having holes 17 near its opposite ends for passage of bolts therethrough, has-a middle p opening or passage 18 adapted to register with'the interior passage formed bythe carburetor and intake manifold. Across the Will be deflected from the middle of the manifold toward the'side wall thereof. The deflector provides a downwardly extending stem 21 which is permanently mounted upon the said bridge in fixed relation to the body portion. 2

By the construction so far described, I pro vide mechanical means for interrupting the passage of fuel for purposes of more thor- V oughly mixi'ngthe same and diffusing or breaking up the stream of fuel'in passing 5 into the intake manifold. The construction is such that the fuel is also deflected from the 1 center of the manifold toward the side walls thereof, and as the sidewall ofjthe intake manifold of an internal combustion engine becomes hotin use, the fnelis vaporized very quickly and effectively by forced contactwith the said wall. This vaporization is conclu-. sive of less fuel loss and greater efficiency in theengine. r 1 Additional means may be provided for breaking up the fuel stream, and for that purpose'I have shown the upper face of body portion 10 provided with grooves 22 from the outer edge thereof to themiddle opening 18. A limited air jet may therefore be drawn 7 into the fuel passage through these grooves and the cross-current thussetup by the air jets will have a beneficial effect in breaking up the fuel stream and aiding in the vaporization process.

Iclaim: V

A device as characterized comprising a substantially flat body portion adapted to be positioned between the flanges of an'intake manifold and acarburetor, said body portion having a middle opening, grooves in the body portion extending from the outer edge to the said middle opening to permit entry of air therethrough, an upwardly projecting support extending from and integral thereto and centrally positioned from said body portion, andja deflector having a'downwardly extending stem adapted to be mounted on said support, and said deflector at its underside sloping upwardly outward so that fuel from the said manifold and air fromthe grooves will deflect the fuel from the middle of the manifold towards the side wall thereof. 7 g V GEORGE E.
